Jewish Festivals: Musaf: Additions for Sacrifices: Sukkot: Outside Eretz Yisrael

Since two days of Jewish festival are observed outside of Eretz Yisrael, read the lines for the sacrifice for both days that might have been the correct day.
Exception On second day of Sukkot, repeat the same lines said on the first day.
Example On the 4th day of Sukkot (the 2nd day of chol ha'moed), say the lines for the 3rd day and 4th day. On Shimini Atzeret, say only the lines for Shmini Atzeret.
